(Mule train mail) author's note ("The village of Supai is located on the Havasupai Indian Reservation at the bottom of the Grand Canyon. The only way in or out is by foot, horse, mule, or helicopter. Since 1896 the mail has been delivered by mule train. Led by a skilled muleteer, the mules make the eight-mile trip from the top of the canyon to Supai in three hours. ... I began the trip by following a mail truck from the post office in Peach Springs, Arizona, to the south rim of the Grand Canyon. There we met Anthony Paya, lead muleteer. Anthony tied the boxes of mail onto the mules ... When the team was ready to go, we mounted our horses and followed Anthony into the canyon.")
